Thanks for letting me know. I had run the thread for awhile, with varying results, mostly the same as mine. I was trying to prove the book was wrong, in order to contact the publisher in hopes of getting future issues corrected, and letting folks here know of the problem. I am confident in the consistancy of my results on multiple, good running bikes ignitor boxes with various meters. The problem came when at least one or two trusted posters, claimed their results matched the book. For pins 4 and 5, if I reversed the polarity, I was much closer to the posted results. I may persue this with the publisher just to get their input.
